sections composed of intermeshing helical wires of left-hand twist.

Conveyor belts composed of Woven wire fabric are frequently made in sections alternately of right and left-hand twist so as to avoid the tendency of such a conveyor to creep laterally upon its supports when in use. According to my present invention, I join the edges of such sections together by means of a bar or strip of metal or other suitable material having a series of perforations adapted to engage the convolutions of a right-hand wound helical wire and another series of perforations adapted to engage the convolut-ions of a left-hand helical wire. The perforations of the two series are preferably staggered with respect to one another so as to maintain the convolutions of the two wires in substantial alinement length- Wise of the fabric and thereby to maintain in alinement the edges of'the sections of fabric that are so joined.

In the accompanying drawing:

Fig. 1 is a plan view of a connecting member constructed in accordance with my in-' vention, showing portions of adjacent woven wire sections which'are connected thereby;

Fig. 2 is a longitudinal sectional view taken on the line 2-2 in Fig. 1; and I a Fig. 3 is a transverse sectional view taken on the line 33 in Fig. l.

In the drawing, the numeral .2 indicates part of a section of wire fabric composed of wires having right-hand twist, and the numerai 3 indicates part of a section composed of wires having left hand twist. A connecting or splice bar 4 joins the end wires 5 and 6 of the sections 2 and 3. For this purpose, the bar 4 is provided with openings arranged in two longitudinal series 7 and 8. These openings are preferably parallel and are inclined to interengage properly with the loops of the adjacent wires. The openings 7 and 8 are staggered with respect to one another, as shown in Fig. 1, so that the several loops of the wires 5 and 6 are in substantial alinement lengthwise of the fabric.

Fig. 2 shows the manner in which the :bar, as shown in openings maybe drilled in the bar 4. The inclination of these openings from the vertical forms a good bearing for the portions of the wires which pass through the openings 7 and 8. It is preferred that the openings 7 and 8 be countersunk'on both sides of the Fig. 2, in order that the openings mayada'ptthemselves readily to the curved surfaces of the wires; 1

In connecting sections of woven wire fabno by means of the sp'lice'bar described above, I prefer to employ the method described in the copending application for Letters Patent of John C. Anderson, filed January 28, 1925, Serial N 0. 5,281, whereby the sections to be joined are laid on opposite sides of the connector, which in this instance is the splice bar 4, then on one side there is screwed into the right-hand woven section, and into the adjacent series of openings 7, a helical wire of the other right-hand wires composing this section. By a similar operation, the lefthand wound section is joined to the connecting bar, and the ends of the connecting wires are bent over in the same manner as the ends of the other wires composing the fabric. I

Modifications may be made in the construction herein shown and described, within the scope of the appended claims.

I claim as my invention:

1. A connector for joining a wire wound in right-hand eonvolutions to a wire wound in left-hand convolutions, comprising a member having a series of openings for engaging the convolutions of the right-hand woven wire and also having another series of openings for engaging the convolutions of the left-hand woven wire.

2. A connector for joining a wire wound in right-hand convolutions to a wire wound in left-hand convolutions, comprising a bar having two longitudinal series of openings, one series for engaging the right-hand woven wire end and the other for engaging the lefthand woven wire, the openings of the two seriest being staggered with respect to one anotlfer, so as to maintain the convolutions of the two wires in substantial alinement in a direction perpendicular to said bar.

3. A connector for joining a wire wound in right-hand convolutions to a wire wound in left-hand convolutions, comprising a bar having a longitudinal series of openings inright-hand twist exactly like having two longitudinal series of openings,

the openings of one series extending obliquely through the bar for engagement with the oonvolut-ions of the right-hand helical wiigi, and the openings of the other series extending obliquely through the bar and parallel to theopenings of the fi-rstnamed series, for engagement with the convolutions of the left-handhelical wire,'-the openings of the two series being staggered with respect to one another, so as to maintain the convolutions of the said wires in substantial alinementin a direction perpendicular to said bar.

the openings ot oneseries extending obliquely through the bar for engagement with the convolut ons of the right-hand helical wire, and the openings of the other series extending obliquely through the bar and parallel to the openings of the first-named Series, 'for engagement with the convolutions of the left-hand helical wire, theopenings of the two series being staggered with respect to one another. so as to maintain the convolutions of the said wires in substantial alinement in a direction perpendicular to said bar and the said openings being countersunk'on both sides of the said her.
